Good question. I was told from my sleep study that I have Upper Airway Resistance Syndrome. The pulmonoligist explained it to me but with my memory the way it is I CRS as to what he said. One of the things I remember his saying when you have sleep apnea and wake up you remember waking up. With UARS you wake up but you don't remember it. From what I've been reading though is UARS can cause other conditions to worsen high blood sugars, high blood pressure and alot of other things besides the daytime tiredness and fatique.
My pulmonary function test showed a decreased difusion capacity and stated: An isolated low diffusion capacity suggests the possibility of pulmonary vascular disease, such as pulmonary hypertension, chronic pulmonary emboli and sleep apnea. And Clinical correlation is recomended. So with all that being said, I am being referred to a cardiologist and have to have an EKG, and an Echocardiogram this week then see both the pulmonoligist and cardiologist. My guess is it will be my congestive cardiomyapathy stiring up trouble again. So we shall see what they do about it. I do know when I've used ET's CPAP I felt like I could breath better, like my lungs were getting more air... hard to explain. ... so we'll see. Nothing ever goes by the book for me medically.. For instance when I had a heart Muga scan. One of the things that test does is see what your ejection fraction is (The about of blood your heart should pump out.....I believe the normal heart pumps out between 60-70% of the blood that was pumped in. On my test it said my Ejection Fraction )(EF) was 27%.... ok so I walk down the hall to get an echocardiogram and they said it was 60%......Go to the doctors office and he sees both tests taken maybe 30 minutes apart !!! He didn't know what to say because my symptons were equivelent to 15% EF. He just shook his head..Then when I had the Muga scan repeated it was 37%(improved by being on meds) and then come to find out they LOST the first 27% Muga scan ........So I guess the question is will they be able to put their heads together and figure out what is causing what and how to treat me. Ok, I'm rattling on the influence of ambien here. I keep falling asleepzzzzzzzzzzzzzzzzzz
